No Power to Cerebus® System
In the event that the Cerebus® system does not power on, check the following:
1) Verify that the Cerebus® system is plugged into a working outlet or power strip, and verify that all power cords are
plugged into the Cerebus®.
2) Verify the position of the power switch and make sure it is in the ON position. If the power switch is in the ON
position, turn it to the off position then wait at least five seconds before turning the NSP back on. (It is recommended
that when restarting the NSP, always wait at least five seconds before turning the unit back on. This will ensure a
proper system reset.)
3) Contact support by sending an email to [e-mail] for assistance.
The NSP Stuck in Initializing
If the NSP is stuck in initializing mode contact support by sending an email to [e-mail] or
calling [phone] for assistance.
Lost Packets Error Notification
If an error message is displayed that network packets were lost during analysis or recording, or that no packets are
being received when running Cerebus® Central, verify the following:
1) Check the Ethernet Cat5E/6E cable and verify that it is secure in the 1 Gigabit Ethernet card in the PC and the RJ-45
port on the back of the Cerebus® labeled “To PC.”
2) Look at the Central Control module and verify that the PC system load is not too high. If the PC system load is too
high, adjust the thresholds on all channels to lower the load on the PC or lower the sample rate for continuous
waveforms if they are enabled.
3) Are any other programs running on the Cerebus® PC? If so, close any open programs that do not need to be running
while using the Cerebus® system.
4) Does the Cerebus® PC meet the minimum specifications for the Cerebus® system? See the manual for PC specs.
5) Is a firewall enabled on the Cerebus® PC? Some issues with firewalls have been known to block data packets between
the Cerebus® system and the PC. Disable the firewall then reboot the Cerebus® PC.
6) Remove any anti-virus programs running on the Host PC. An anti-virus program can scan all Ethernet UDP packets
and result in a delay in data transmission.
7) In Windows Vista or 7 disable sound through control panel => System Manager.
8) Check to see Windows Defender and Windows Restore are running and disable if necessary.

No Neural Activity on any Channels
If Cerebus® is turned on and running but there is no apparent activity on any of the channels from an implant or
from the simulator, verify the following:
1) Open Central.exe and verify that packets are being received from the Cerebus® system. If the PC is not receiving
packets from the Cerebus® system, see troubleshooting section “Lost Packet Error Notification” above.
2) Verify that the fiber optic data link between the Amplifier and the Cerebus® NSP is plugged in and that the green light
next to the fiber optic data port on the NSP is illuminated. If the light is red, there is no fiber optic link present. Check
the LED next to the fiber optic port on the back of the Amplifier to verify that it has power. If the LED is not
illuminated, check the APS and verify that it is turned on and not in standby mode. Are the cables securely plugged in?
